. w Thisinvention relates tolbottomfbars for yc-urtains, particularlylthosethat are used for the windows `of railroad cars, and has for its object to provide a hollowv bottom bar,- made from `a single `piece Aofesheet. metal, -.and

wfurthermore, to secure `the loweredgeo'r"` the curtain within this bar `without thelemployment of any such .means `as screws or; rivets. Y.

` .Anadditional'object is to so equip the b ottom of a curtain that. it willharmonize with i -n VIn the accompanying drawingswhich form `apart of:v this application Y 15 Figures 1,2 and 3, are cross sectional views `.showing various waysv of securing thebottom edge of 'the i curtain within` the curtain bar, in

l Similar numerals of reference- `denote like f parts inthe several figures ofV the drawing.

' We have illustrated 'several ways of securing` the bottom edge of theicurtain to thebottom bar, and they will be hereinafter described. All, oftheseforms of the invention show a de ormationof the upper edges of the bottombar and the employment of separate means applied to the edges in such a manner `as to prevent undue spreading of saidedges. The curtain'is therefore firmly heldin position. Vhile we have shown deformations on l the edges of the bottom bar, we desire to have it understood that any arrangement whereby the curtain is 'frictionally held in place comes withiuthe scopeof the broadest claims.

1 is the curtain and 2 the hollow metal bottom bar whichis of any suitableshape in cross section and whose edges termmate at the top of the bar. g

In Figure 1 the edges of thev bottom bar 2 are curvedoutward'lyto form curled edges, as

shown ati-3, and the lower edge of the curtain is doubled lso as to form a hem, this doubled edge being vstitched together, as shown at a, and within this hem is inserted a keeper rod 5, and a metal member 6, closely'A lower end around the curi conforming at its tain hem, is inserted within and preferably `entends throughout `the length ofthe bar 2.1

The upper side` portions 7 of this :member 6 curtain .in position.

tain is `frictionally held,` between the upper edges of the b`ar2, although the member 6 is interposed between thecurtain andthebar 2. In theconstruction` shown at Figure 2, the edges of the bottom barare bent'downwardly at .8 `and terminate in outwardlyV curved porx tions` 9` which closely embrace the hem 4 of the curtain and cause it lto closelyhugthe retaining rod 5. The clamping means,pref-:` erably a strip 10, is passed through thejbar 2.

so as to embracethese curved portion`s`9 on the bottom bar to hold said portions firmly.

`The upper edges of the bottom bar are thereby prevented-from spreading when strain is put upon `the curtain. f

InF'gureB` isshowna Vconstruction inV which the" upper edges of thebottoin bar,` are bent inwardly and terminate in short outwardly `extending lips 11. ."Ihe curtain is embracedbetween these edges `of the bottom the h em of thecurtain as in the `constructions 'above described. Clampingmeans, preferaa vcircular strip 12, whosegupper terminals .ba-1 ',lthe retaining rod being inserted within extend inwardly, firmly clamps the lips 11.."

This means is inserted within the bar 2 and servestoprevent theupper edgesoffthe bar `2` from spreading when .strain is` brought to `bear on thelcurtain. y y Y y,

l In the constructions" abovedescribed, a

stitched hem.` is` formed atthe bottom `edge of the curtain'for theinsertion of the vrod 5, but, while this is preferred, it is not necessary. The stitching, as in Figures`4 to `Sinclusive,

and the stitching as well as the rod, as in Figures 5 to 7 inclusive, may be omitted. The constructions shown in these figures will now be described.

The construction shown in Figure lis like that shown in Figure 2, with the exception that in the former there is no stitched hem, the curtain being merely wrapped around the rod 5.

In Figure 5 the downnnrdly bent edges 8 of the bottom bar terminate in parallel concavo-convex deformed portions 15, 16, between which the lower edge of the curtain is embraced. Clamping means, preferably a strip 17, closely conforms to said deformed portions and is placed on said portions so as to grip them and thereby bind the curtain securely between the edges of the bottom bar.

The construction shown in Figure 6 is like that shown in Figure 3, except that the former omits the hem along the bottom edge of the curtain and also the rod 5, and shows the curtain confined by the inwardly extending portions 8. rlhe clamping means, preferably a strip 12, engages against the lips 11 and assists in firmly holding the curtain between the edges of the bottom bar.

Figure 7 shows the downwardly extending edges 8 with abrupt inwardly extending V- shaped deformations 18. The curtain is gripped between said edges 'and deformations,I and the clamping means, preferably a circular strip 12. is placed' in the bar 2 with the terminals of said strip firmly engaged with the outer surfaces of these deformations, to thereby secure the curtain.

Figure 8 shows a construction like that shown at Figure 1, except that inthe former the stitched hem is omitted, the lower edge of p the curtain being merely wrapped around the rod 5.

In all of the constructions shown in the eight figures of the drawing. the lower ede'e of the curtain is frictionally confined between the upper edge portions of the bottom bar, and clamping or retaining means is employed to make sure that the upper edges of said bar are prevented from spreading.

llVhat is claimed is 1. A bottom bar structure for curtains consisting of a hollow bottom bar made of sheet metal having its edges at the top, intermediate of which edges the lower portion of the curtain is held by friction, and means for preventing the edges of the bottom bar from spreading.

2. A bottom bar structure for curtains consisting of a hollow bottom bar made of sheet metal having its edges at the top, betweenv which edges the lower portion of the curtain is held, means to assist in frictionally holding said curtain in Contact with the bottom bar, and means for holding the edges of the bottom bar from spreading.

3. A bottom bar structure for curtains consisting of a hollow bottom bar made of sheet metal having its edges at the top, between which edges the lower portion of the curtain is held, means to assist in frictionally holding said curtain in contact with the bottom bar, and a clamping strip for holding the edges of the bottom bar from spreading.

4. A bottom bar structure for curtains consisting of a hollow bottom bar made of sheet metal having its edges at the top, between which edges the lower portion of the curtain is held, said edges having deformations, and means for holding said deformed edges from spreading.

5. A bottom bar structure for curtains consisting of a hollow bottom bar made of sheet metal having its edges at the top, between which edges the lower portion of the curtain is held, said edges having deformations, and a keeper strip for holding said edges from spreading.

6. A bottom bar structure for curtains consisting of a hollow bottom bar made of sheet metal having its edges at the top, between which edges the lower portion of the curtain is held, said edges having deformations, and

a retaining strip conforming to said deformations and holding said edges from spreading.

7. A bottom bar structure for curtains, consisting of a hollow bar made of resilient sheet metal having its edges at the top and terminating in deformations, a curtain having its lower edge stitched to form a hem and depending within said bar intermediate of said edges, a retaining rod within this hem, and resilient means for clamping said edges to prevent the spreading thereof.
